$A$ light ray is incident on an equilateral glass prism placed on a horizontal table. Which of the following is true for the condition of minimum deviation?

Calculate the angle of minimum deviation for an equilateral triangular prism of refractive index $\sqrt{3}$. (in $^{\circ}$)

Obtain the relation between incidence angle,emergence angle,prism angle,and deviation angle for refraction through a prism.

The angle of a prism is $A$. One of its refracting surfaces is silvered. Light rays falling at an angle of incidence $2A$ on the first surface return back through the same path after suffering reflection at the silvered surface. The refractive index $\mu$ of the prism is

$A$ ray of light is incident at an angle of $60^o$ on one face of a prism of angle $30^o$. The ray emerging out of the prism makes an angle of $30^o$ with the incident ray. The emergent ray is

For refraction through a small angled prism,the angle of deviation:
